Stock Vs Aftermarket Rotor Weight Does anyone know how much the stock rotors (front and rear) and stock calipers weigh?
What about aftermarket units? I have Stoptech 13.5" slotted rotors and 4-piston calipers on the front (came with the car) and I was just curious.
So here's the real question: Are these aftermarket units lighter or heavier than the stock ones? I know they're bigger, but I don't know if they're made out of different material, etc . . .
Thanks!

I am not sure but I have seen a dyno on a show that they lost a slight amount of horsepower due to larger rotors even though the aftermarket ones they chose weighed the same as the stockers. The larger aftermarket rotors ended up taking a few ponies due to centrifical force as they are larger in diameter. No info on the weights though.
